Keeping your electrical systems in top shape entails commissioning regular tests and evaluations to spot existing and potential faults. However, the conventionally used method of physically inspecting and testing electrical equipment can be expensive and time-consuming. And, the chances of errors in testing cannot be entirely ruled out in such a case. The good news is that companies are increasingly turning to a better, more efficient testing alternative in the form of infrared imaging-based testing that is referred to as an Infrared Electrical Inspection.
Where can you apply this testing technique?
Infrared Electrical Inspection is a very comprehensive system that can be applied on electrical generation, distribution and production equipment such as:
Electrical utility substations, transformers and feeder poles
Main electrical incoming services, transformers, capacitor banks, etc.
Main electrical switchboards and disconnects
Main electrical distribution panels and disconnects
Uninterruptable electrical power supplies
Generator controls and transfer switches
Main I-Line electrical panels
Lighting and receptacle electrical panels
Motor control centers
Service electrical disconnects for motors
Bus ducts
This is an inspection process that is carried out by certified thermographers using highly specialized tools and systems. There are several benefits of an infrared electrical systems survey. Here are a few of them:
A large amount of electrical equipment and components can be tested in a short period of time.
Infrared testing will find problems that are not typically found during a general shutdown and visual maintenance inspection. Items such as bad breakers, phase imbalances, cross threaded bolts and overloads are detected with infrared imaging but not normally found during a general shutdown inspection.
The real test of the efficacy of a preventative maintenance program is its ability to find faults before they cause serious damage. With an Infrared Electrical Systems Survey, you âEUR~find your problems before they happenâEUR(TM).
An infrared electrical systems survey must be carried out under normal operating load. In contrast, a physical inspection of electrical systems calls for part (or total) power shutdown that can cost thousands of dollars. The infrared electrical inspection is done during normal working hours and under normal load conditions.
Infrared thermography testing is not only non-contact; it is also a non-destructive testing method. So, it does not affect your normal operations. Given these advantages, one might assume that Infrared thermography testing would be an expensive service. If corrected, the problems found during a survey will greatly reduce the possibility of an unschedulued outage, equipment damage and/or an electrical fire. The prevention of any one of these possibilities is well worth the small cost of the Infrared Electrical Systems Survey. Some of our clients say âEURoeit is the cheapest insurance money can buyâEUR
